Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

MayaTool: Missing Joints in the influence list

Hi all

Ive been working with the toolkit a lot now, going back and forth, setting up joints, painting weights etc. Not considering minor bugs and well known issues, everything worked very well. Congrats at that point! Today i was working with the tool again, i went back to the skeleton creation tab to add some joints to my rig. Now when i switched back to the deformation setup, the influence list (joint list) for the weight painting doesnt show all the joints anymore. But: The joints exist, in the viewport as well as in maya`s outliner. So is there a fix, has this happened before? I can not paint weights on the missing joints which means i can not proceed.

Any help is much appreciated.

Using Maya 15 on a Windows machine.

I found a solution that worked for me. It`s a temporary workaround though so a fix would still be nice.

To fix the issue all you need to do is select all the joints you are missing in the influence list, then shift+select the mesh, go to the "skin" tab and choose "add influence" from the dropdown menu. you should now see the former missing joints in the influence list.

But here is the downside:

Once the joints are added to the influence list, the skin weights are lost and you will not be able to import them if you exported before adding the joints to the influence. So be carefull using this methode or do it before you start painting weights.

This is not a permanent solution - the problem reoccurs. When opening my file later, one joint was missing again, and the weight it used to have, was redistributed, completely messing up the weight paint across several joints.

Hey DAkAR -

The Animation and Rigging Toolkit for Maya has not yet been tested in Maya 2015. Support and fixes coming shortly. However if the joints exist in the Maya heirachy, you should be able to paint the skin weight in with the Maya paint tool outside of the toolkit.

Also keep checking this **forum link** for updates and information about the ART.

Thank You

Eric Ketchum

Hi Erik.

Thank you so far.

I should have mentioned that i already tried what you suggested, using maya`s weightpainting options. Also I check that dropbox link almost every day but with no luck so far. But I had the same problem. Anyway. Thanks again. Guess I will be waiting then.

Heya! So, what the tool currently does is when you go back to edit placement or skeleton settings, it will save out your weights that you had on any meshes. When you come back to deformation setup, it will import those weights and remove any unused influences. This is probably why they are disappearing from the influence list. You can use the Add Inf button above the import/export buttons on the toolbar instead of using Maya's. This will ensure it will keep your existing weights and simply just add the influences to the list for weighting.

I'm using maya 2019, i've resolved opening the paint weights tool, selecting a bone, the select the mesh and click on the brush button on ARTv1. Now the bones are showing in the Influence list and you can close the maya's paint weight tool.

Hope this help you guys.
